6.1.2 Detector
Procedure see point 6.1.1, but instead of the alteration of the setting ring, the intended
setting is done with 11-box spanner or 8-key wrench.
Before you must remove the black ring (Pos. 50.13, Fig. 6) through pulling off, and then
push on after setting.
6.2 Setting correction
- Loosen the body screw (M4).
- The correction is done through turning the body (pos. 50.5) till the setting is equal to the
actual temperature (actual value on control manometer). The setting ring (pos. 50.13)
(tools with detector) must be held; it is not allowed to turn.
- Set to the needed value.
(Turn the setting ring (pos. 50.13) (tools with detector) - Hold body (pos. 50.5)).
- After the temperature regulation in the system had been fulfilled, read again the actual
temperature.
- If both values are the same, the procedure is ended.
- If the value has not been successfully reached, repeat the setting correction.
- When the correction is done, turn the body (pos. 50.5) so far, that the setting range can be
seen, then fasten the screw.
7.0 Care and maintenance
Maintenance and maintenance-intervals have to be defined by the operator according to
